Application filed October 19, 1923. Serial No. 669,595.

To all whom 2'25 may concern Be it known that I, L W L W. SHIELDS, a citizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in VVork- Holding Means for Stapling Machines or the like, of which the following is a specification.

The present invention relates to work holding means for stapling machines or the like, and an object thereof is to provide a work holding means which will hold a loop, such as employed on belts and other leather straps, harness or the like, so that it will'be properly stapled and may thereafter be fed to a receiving bar.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described; the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a side view of the upper portion of a stapling machine of a known construction with the work holding means attached thereto; 7

Fig. 2 is a perspective view of the anvil;

Fig. 3 is a sectional view through the anvil; I

Fig. 4 is a perspective View of the retaining means for holding the loop on the anvil; Fig. 5 is a perspective view of the receiving bar; and

Fig. 6 is a section on the line 66, Fig. 3, showing a loop in position on the holding means.

The stapling machine may be of any suitable construction which will drive a'staple preferably formed of wire or a sheet metal strip, the machine shown being what is knowncommercially as the Latham Monitor wire stit'cher.

3 arranged below the overhanging portion. The overhanging portion carries a hammer 4 and suitable staple forming material (not shown) all of which is old.

On the table 4. is supported an anvil 5 in the upper surface of which is arrangeda removable die 6 for bending inwardly the end of the staple. The anvil 5 overhangs a base portion 7 which by a screw 8 is detachably surface of the ext This machine has a base. 1 with an overhanging portion 2 and a table sec re o the. table O ing t e n i is a retaining means preferably in the form of arms 9 spaced apart at 10 and resiliently supported by a loop 11 from a detachable portion 12, which is secured to the inner side of the anvil. A loop 13 of leather or other suitable materiahis bent about the anvil in the manner shown in Fig. 6 with the ends bent inwardly under retaining means 9, the extreme ends being situated between the recess and over the die 6. The stapling machine forms a staple and drives the same through the ends of the loop, the ends of the staple being deflected inwardly by the die 6, thereby forming the loop.

To the end that the end formed loops may be readily handled in the future use thereof, a loop receiving means is provided in the form of a bar 14, the cross section of which is slightly less than the cross section of the opening through the loop. This bar 14 ex- 7 tends, from the free end of the anvil in line with the latter and is preferably detachably connected with the anvil. In order that this retaining bar may be detachably supported from the anvil, the latter may have an extension 15 at its free end and an overhanging or undercut portion 16 at the inner end of the extension. Projecting from the top nsion is a pin or projec- The receiving bar has its inner end bevelled at 18 to extend under the overhanging or undercut portion 16 and is also provided with an opening 19 near said bevelled end for receiving the projection 17. It is apparent that the bar may be readily fitted or removed from the anvil by swinging the latter vertically about the inner end as a pivot, so as to engage over or slip from the projection 17. When in position, the projection lies in the opening of the receiving bar, and the anvil will prevent any lateral movement of the receiving bar.

From the foregoin it will be seen that there has been provided a work holding tion 17.

means for a stapling or like machine esform of a recelving bar detachably connected to the anvil so that the bar may be utilized for feeding the loops to other machinery.

What I claim as my invention and desire to secure by Letters Patent is:

1. A work holding means for stapling machines or the like comprising a base portion, an anvil overhanging the base portion about which the loop forming piece is adapted to be passed, a die in the upper surface of the anvil, and a receiving member for receiving a plurality of stapled loops detachably connected to the free end of the anvil in line therewith.

2. A work holding means for stapling machines or the like comprising a'base portion, an anvil overhanging the base portion about which the loop forming piece is adapted to be passed, a die in the upper surface of the anvil, an extension on the free end of the anvil provided with a projection, an overhanging portion at the inner end of said extension, and a receiving member for receiving a plurality of stapled loops having an opening receiving said projection, and an end extending under the overhanging portion.
